Computers/Data
Computer applications for distance education include:
- Computer-assisted instruction (CAI) - uses the computer as a self-contained teaching machine to present individual lessons. One example of CAI would be a course that uses a CD-ROM.
- Computer-managed instruction (CMI) - uses the computer to organize instruction and track student records and progress. The instruction itself need not be delivered via a computer, although CAI is often combined with CMI.
- Computer-mediated
education (CME) - describes computer applications that facilitate
the delivery of instructions. Examples include; electronic mail, fax,
real-time computer conferencing, and World Wide Web applications.
